Marriage is a covenant "by which a man and woman establish between themselves a partnership for the whole of life" (Catechism of the Catholic Church, #1601). Usually we think of this covenant in a rather personal and individual context: It exists for the good of the spouses and the good of their children. We sometimes think of the wedding ceremony, which establishes this covenant as belonging to the bride and groom, as if it were their wedding alone. The Second Vatican Council reminds us that the marriage covenant exists not only for the good of the partners and their children, but also for the good of the Church and the good of society at large (see Church in the Modern World, #48).
At Transfiguration you are asked to contact Fr. Rob or Deacon Eric at least nine months in advance to arrange a tentative date.
